Partial tuning maps for 91 octane CA gas
 

Attached are some maps you may find interesting. Apparently 91 octane CA gas is roughly equivalent to 89 octane FL gas. The stock interceptor map has too much timing and you get detonation. During the tune process we took out ~5 degrees of timing with no real change in the HP curve. According to the dyno guy that means the timing was too aggressive for our gas.

The maps are for a greddy turbo running 7psi max, no boost controller. Target AFRs in mid- to upper-10's. Hopefully this weekend I'll be able to finish the tune, targetting 10psi.

I'll post mine tonight if possible. I actually had to take out more timing since I was running (and able to hold) higher boost levels.
